I replaced the power steering hoses on a 2004 Trailblazer. The manual states that it uses 89021184, which is an obsolete product. According to GMPartsPrime.com, 89021184 and 89021185 have been replaced by 19329450. Note this is a 1 pint size. It took 2-1/2 pints to fill my car. The oil was blown out of the radiator and the rail was stroked to force all the old liquid out.
